Log-in failure: `invalid data, try again format must be 'user@server/resource'`

[barracuda156]

@hannesm Sorry for a silly question, I have finally built jackline, but it does not want to accept my ID:

Welcome to Jackline configuration. You will be guided through the setup.
Jabber ID: 
 
invalid data, try again
format must be 'user@server/resource'

The account itself is working. Am I doing something wrong?

[barracuda156]

I try using username@server format, to no avail.

I have checked now with profanity client, and my credentials work as expected.

Thanks a lot for your interest in Jackline. It requires not only your XMPP id, but as well the resource be specified explicitly -- so instead of my_user@server.org, you need to say e.g. my_user@server.org/jackline. The resource in XMPP is used for distinguishing different clients in case you are logged in multiple times with the same account.

Maybe that is the issue?

@hannesm Indeed, that got me here:

Port: 5222 (default)
Password: 
*****
Certificate fingerprint (leave empty to instead specify CA file): 
 
If you have `tlsclient` installed, run: `tlsclient -z --starttls=xmpp ${myserver}:5222`
Alternatively: `openssl s_client -connect ${myserver}:5222 -starttls xmpp | openssl x509 -sha256 -fingerprint -noout` (add -xmpphost ${myserver} if available)

Running the suggested command from another window gives an error:

C0AD920F01000000:error:8000003D:system library:BIO_connect:Connection refused:crypto/bio/bio_sock2.c:178:calling connect()

But I guess I need to check documentation how to set it up.
